Controlled by the engine’s electronic control unit, the sealed Modulator LCV40 Fan Drive is built for high torque and a faster response time, with variable-speed operation and lower off-speed to help facilitate more usable horsepower for auxiliary systems.

WindMaster LS11 blades, constructed with UV-stabilized materials, can be trimmed to the appropriate size for radiator and airflow requirements and are computer-optimized for minimum deflection, reduced fan stress and increased airflow stability.
